手段であると一般に言われている。<Conventional technology> Along with recent advances in defense technology, there have been remarkable advances in detection and reconnaissance technology.
In addition to methods that use ultraviolet rays, radar waves, etc., far-infrared M
The K method is attracting attention. In particular, this method differs from conventional methods in that it captures and visualizes far-infrared rays (commonly called heat rays) emitted by detection and reconnaissance objects. Detection and reconnaissance is possible regardless of the location, and since far-infrared rays have long wavelengths, it can detect fog,
It has the feature that it is not easily affected by smoke, etc., and is generally said to be an extremely preferable method for reconnaissance of military objects such as tanks and airplanes.
探知・偵察技術とそれを隠蔽する偽装技術は関連があり
、新しい探知・偵察手段が登場するとそれを偽装する手
段が強く求められる。Detection and reconnaissance technology and camouflage technology to conceal it are related, and when new detection and reconnaissance methods appear, there is a strong need for methods to disguise them.
現在、遠赤外線探知・偵察よシ軍事対象物を有効に偽装

まなアルミ箔等においては軽量で操作性には問題はない
ものの、他の偵察手段、例えば目視（可視光）手段に対
し、輝くため、好ましくない結果を与えている。Currently, various methods have been proposed for far-infrared detection/reconnaissance and for effectively disguising military objects.
Alternatively, a camouflage sheet using aluminum foil or the like with low far-infrared radiation is known, but the heat insulating cloth has problems in terms of operability in covering and camouflaging a tank etc. with the sheet in a short time.
Aluminum foil and the like are lightweight and have no problem with operability, but they shine and give unfavorable results to other reconnaissance means, such as visual (visible light) means.
さらに、これらのものは通風性がなく風にあおられ易く
、屋外に設置された場合その状態が安定せず時によって
は破損することがあり、風の中での展張作業も困難な場
合がある。Furthermore, these items do not have ventilation and are easily blown away by the wind, so if they are installed outdoors, they may not be stable and may even break, and it may be difficult to expand them in the wind. .
〈発明が解決しようとする味題〉

い。<Problem to be solved by the invention> As described above, there is a strong need for a means of disguising far infrared rays that is effective, easy to operate, and has excellent ventilation.
At present, no useful camouflage material has been found that satisfies these requirements and does not adversely affect other detection and reconnaissance means.
＜ｙＡ題を解決するための手段〉
本発明は、合成樹脂製テープが編織されたシートからな
り、該テープが捩れていることにより不シートである。<Means for Solving the Problem yA> The present invention is made of a sheet made of a woven synthetic resin tape, and the tape is twisted so that it is not a sheet.

る。First, the sheet of the present invention is appropriately knitted from synthetic resin tapes, such as tapes made of film or ribbon tapes made of knitted fabric, and the tapes are twisted so that each tape surface is oriented in a random direction. The sheet has an irregular surface (or back) structure and adequate ventilation.

面構造を取シしかも十分に通風性を有したものとなる。A sheet having a structure in which each tape surface is oriented in a random direction as described above can be made, for example, by inserting the tape as a weft to form a raschel knitted fabric. In this case, the tape is twisted to an appropriate degree when it is inserted into the chain stitches of the knitted fabric, and the tape surface is oriented in random directions between the chain stitches, resulting in a twisted pattern. FIG. 1 is a plan view of the sheet of the present invention showing its state, and FIG. 2 is a cross-sectional view taken along line A-A thereof, in which numeral 1 shows a synthetic resin tape and 2 shows ordinary warp yarns constituting a chain stitch. As shown in Figure 2, the sheet of the present invention shown here has the tape surface facing in a random direction, and as a result, the sheet has an irregular surface structure and has sufficient ventilation. Become.

るか、平行に並べられ念糸。In addition to the methods described above, methods for obtaining the structure in which each tape surface of the present invention is oriented in random directions include creating a coarse woven or knitted fabric using loosely twisted tapes as warp and/or weft threads, or creating a coarse woven or knitted fabric using loosely twisted tapes as warp and/or weft threads, or Nenthread.
テープ等あるいは粗目の編織布の面に、緩く捩つ九テー
プを並べて接着する方法がある。There is a method of arranging loosely twisted tapes and adhering them to the surface of tape or coarse knitted fabric.
本発明のシートは前記のような構造を有し、遠赤外線の

るいは拡散され、これによシ遠赤外線の直進透過が著し
く阻止されるものと考えられる。The sheet of the present invention has the above-mentioned structure and has a straight far-infrared transmittance of 20% or less, and if the transmittance exceeds 20%, a sufficient far-infrared barrier effect cannot be obtained. According to the structure of the present invention, a part of the far infrared rays emitted from the heat source is randomly reflected on the tape surface constituting the sheet of the present invention, and a part of the far infrared rays is refracted and transmitted according to the respective incident angles, Furthermore, some of the far infrared rays are absorbed by the tape itself, and as a result, the far infrared rays emitted from the heat source as a whole are dispersed or diffused in random directions by the sheet of the present invention, which significantly reduces the straight transmission of far infrared rays. It is thought that this will be prevented.
なお、本発明においては、各テープ間の間隙率があまり

きい場合には間隙率が小さくても部分的に遠赤外線が直
進透過するため、好ましくは該間隙の幅は２０１１以下
とする。またテープ幅としては２〜１０■が好ましい。In the present invention, if the porosity between each tape is too large, the straight transmittance of far infrared rays may increase depending on the size of each gap. Therefore, the porosity should be set to 50% or less, especially It is preferable to set it to 20 inches or less. Furthermore, in the present invention, if the width of the gap is relatively large, far infrared rays will partially pass straight through even if the porosity is small, so preferably the width of the gap is 2011 mm or less. Further, the tape width is preferably 2 to 10 cm.

A or a surface C that is expected to have a far-infrared scattering effect (such as a film tape with fine irregularities, a tape that has a far-infrared reflective layer on the surface or inside and does not significantly invite detection by visible light, etc.) In particular, in the case of far-infrared absorbing tape, its absorption rate is 55%.
